I have these Halibrand Cobra III Deep Lip 17x9 that I purchased for my GN but decided to go with a black center 18" set up. These are "true" Halibrands with 275/40/17 for the rear and 245/45/17 front. They are FOR SALE if you are interested with ZERO miles (tires are z rated Bridgestone Fuzions wth the stickers still on them!) They fit GREAT and give the car a nice stance. Pictures do not do these wheels justice, the chrome is excellent and makes it hard to get a "detailed" photo. I can get you some close-ups if you are interested. They have billet centers and I have (2) extras just in case. They will also come with lugs, mounted balanced and ready to go.
I forgot to mention. My plan was to have the centers powder-coated black to get the Old-School look and have actual "chrome" lips instead of polished but as luck would have it I found a black center 5-spoke I liked before they made it to the painter.
Seems to me that this IS a RELEVANT post since Ron is seeking info on "COBRA" style wheels, sorry if this has IRRITATED you! They are posted in the Parts For Sale listings.
